科學家尋求阻止衛星相撞

Scientists are making efforts to prevent satellites from colliding in space. A new project at Durham University, which has a budget of £5 million, is focused on improving the management of satellite traffic. According to Professor James Osborn, who is the founding director of the new space research center, the idea that satellites won’t crash into each other just because space is so vast is no longer a safe assumption. He emphasizes that satellites play a crucial role in providing internet access to remote areas, such as Weardale in Durham. In the past, during the 1960s, only a small number of satellites were launched into space each year. However, Professor Osborn notes that in recent years, the number of satellites has dramatically increased due to the availability of reusable rockets. He stated, 'Now it’s thousands of satellites a year. ' This rapid growth in the number of satellites raises concerns about potential collisions. Currently, there are around 10,000 active satellites orbiting the Earth. Professor Osborn explained, 'Nobody knows where they are going at any one moment. ' This uncertainty poses a significant risk, as it can lead to collisions or accidents in space. The new center aims to develop technology that can monitor the positions of satellites to prevent such incidents. Additionally, the team is working on creating new policies for managing space objects, hoping that these policies will be adopted by space agencies and governments. Professor Osborn believes that the ability to create new technologies while also developing policies is a key aspect of the center's mission.
